I was going to mention this one, Fingernail polish works great as a
resist (at least in Ferric Chloride). Dries rock hard in a few
minutes. I've used it to paint large ground planes (really nice since
it comes with a built in brush). Also works good for touch up with a
smaller brush or my favorite, a toothpick.
